Formation of furan and furan derivatives in baby food products

open access: yesFood Chemistry
A comprehensive analysis of 89 commercial baby food samples showed the highest levels of furan in ready-to-eat full meals and vegetable purees (12-118 μg/kg). The alkylated furans (2- and 3-methylfuran, 2-ethylfuran, 2-pentylfuran) were predominantly found in these baby food categories.

Titanium-induced syntheses of furans and indoles

open access: yes, 1991
Aromatic acyloxycarbonyl- and acylamidocarbonyl compounds on treatment with titanium on graphite readily afford (benzo)furans and indoles respectively, by an unprecedented McMurry-type ...

Catalytic Conversion of Glucose and Chlorella Sp. Into Furans in the Presence of Niobium Oxide

open access: yesChemical Engineering Transactions, 2023
A series of Nb2O5 solid catalysts have been prepared to be used for the catalytic dehydration of glucose and sugars from algae Chlorella sp. into added value furans. The glucose transformation gave rise to 5-hydroxymethylfurfural (5-HMF).

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

A Powerful Cascade Approach for Expeditious Synthesis of Trifluoromethylated Furans

open access: yes, 2016
A powerful approach to synthesize trifluoromethylated furans has been developed. The method is operationally simple, broad in substrate scope, and amenable to scale-up using trifluoroacetic anhydride. Meanwhile, the strategy not only provided a versatile
